The New Glarus Brewing Company expansion now rising above the village skyline will do more than increase brewing capacity. It will also introduce a large-scale geothermal heating and cooling system — the first large-scale commercial geothermal system in New Glarus (and possibly Green County, too).

Construction on the 65,000-square-foot, four-story addition began in October 2024 and is expected to be completed in early 2027. The project includes a new brewing area that will double production capacity, a distillery, expanded tasting room, new parking lot and beer garden. During construction, the Hilltop facility remains closed to the public, with the original Riverside brewery serving as the temporary tasting room.
